“As a nation, we recognize the right of all people to believe as they want and not to impose our beliefs on other people,” Romney’s voice is heard saying next –- this comes from an Oct. 25, 1994 Massachusetts senate debate.

“I believe that abortion should be safe and legal in this country,” Romney continues. “I have since the time that my mom took that position when she ran in 1970 as a U.S. Senate candidate. I believe that since Roe v. Wade has been the law for 20 years that we should sustain and support it. And I sustain and support that law and the right of a women to make that choice.”

In 2005, Romney changed his position from supporting abortion rights to opposing them.

Neither the text message nor the automated message gives any indication who sent or paid for the messages.

The abortion issue plays very big with conservatives in Iowa. 2008 Iowa caucus winner, Mike Huckabee, even held a forum and movie premiere in Des Moines this month focusing on abortion. Romney did not attend, although Newt Gingrich, Rick Santorum, Michele Bachmann, and Rick Perry did.
